Mackenzie Frances Ziegler (born June 4, 2004) is the youngest child of Melissa Ziegler-Gisoni and Kurt Ziegler and is the sister of Maddie. Whilst on Dance Moms, Mackenzie was always the youngest dancer on the team. She was often pressured by Abby and Melissa to follow in the footsteps of older sister Maddie. Besides dance, Mackenzie is also interested in music. In 2014, she released her debut album entitled "Mack Z". The album reached #1 on the iTunes pop chart list in America[3], as well as reaching #7 on their overall album charts.[4]. Mackenzie and her family chose to depart from the show mid-Season 6 to pursue other projects. Not long after, the sisters left the ALDC completely and switched to Dance Mechanics.
